Fig. 6. Mean non-acceleration-compensated differential pressure signals for eight
positions (P8, P7, P4, P3, S1, S2, S6, S7) along and across the wing. The
traces are ordered from distal sites at the top towards proximal sites nearer
the bottom, and the synchronising accelerometer trace again appears as the
last trace, in green. Values are mean ±1 S.D. (shown in
black; N=3 pigeons). Signals for the five sites near the leading edge
of the wing are shown in red. Signals for the three pressure sites towards the
trailing edge are shown in blue. Periods of downstroke defined by kinematic
observations of the wrist are shown as grey for two of the middle three flaps.
This shows the close relationship between downstroke timing and the
development of `positive' (ventral-to-dorsal) differential pressures, which
are used to define downstroke periods shown with underlying grey boxes for
take-off and landing. LE, leading edge; TE, trailing edge.
